Tire main body 1 oi the stove Ys made up oi sheet metal, ot one piece, stamped to the substantially rectangular form shoivn in Figs. 2 and 3.

1927. Serial No. 177,987.

lt has but one `ioint as shown at 2, which may be completed by Welding orin any suitable Way. The top portion of this main body countersunk as aty 3to providea slightly depressed top plate for receiving certain ot the heatingelexnents to be supported thereby and tor supporting also a coveisection composed of a top plate i and depending' trout, rear and lateral side portions 5 which have their lower edges beaded as at o to rest with their rounded surfaces upon the corresponding curved margins 3 detining the countersink or depression of the upper wall of the main body of the stove. This cover member is hinged to the main body ot the stove at its rear edge9 so that 'it may be swung up to expose the npperfhez'iting units or elements indicated generally at 10a, 11, 11. located Within the chamber or compartment formed between the said cover f1 and the top plate or portion of the main body 1. The cover plate has openings as at 19 Fig'.` 2 throughr Which the heating elements are exposedon `which utensils are. placed to be heated.

There are four oitl these openings in the` form of the invention chosen for illustration, three of which are shown, and those atthe rear are for the open heating elements which have clay members, in grooves of which members the heating coils are placed, and from which the heatis directed upwardly against the bottom ot the cooking vessels. The two front openings receive plates 1,4, 14a of the heating units instead ofk grates. The plate at the right has a depressed surface and the plate at the left isplain, and both can be used as griddles or serve as heatingl plates for the vessel placed thereon.

The Vfront Wall of the cover member is provided with openings for. the insertion or removal of Wailie irons and a' toaster, into and away from the front heatingr units, the toaster being located at the right hand heating unit, and thev Walle iron being used at the left hand heating unit as shown respectively at 15, 1 6, Fig.'2. y y y The vheating Aunits at the front marked. 11 and 11a are ot an enclosed type in that they do not direct heat up immediately against the vessel as do the rear heating units above mentioned, and it Will be seen from Fig. 2 showing one of these front heating units in section that the plates 14., 14: above mentioned are provided by the upper extensions of the casings of these forward heating units insulation.

which extensions project upwardly through the openings in the top of the cover member in which they closely fit and form closures therefor againstair circulation.

This feature of the top of the heating unit. acting as a closure for the openings in the cover 4 is present at all the heating' 'units to provide for the dead air space within the said cover 4.

Thev front heating units comprise an cnclosing casing which may be made ot upper and lower sections secured together, the bottom of the casing resting on the top plate or portion of the main body 1. Within the casing of the heating units 11, 112t heating or resistance coils 17 are located supplied with current through suitable circuit connections, and there are two series of these coils between which the waiile irons and toaster are received. Each of these heating units is provided with spring contacts as at 18, which engage electric contacts mounted on the top plate of the main body 1, for which purpose spring members 19 are mounted in insulating blocks 19@ secured to the under side of 'the top plate 'L which is provided with an opening through which the spring Contact members19 are exposed to receive the depending spring contacts 18 of the heating elements. All the heatingunits or elements, i. e., both the front and rear sets are provided with these contacts to engage the companion socketed contacts of the top i. All the heating units are protected against drafts and loss of heat by the movable cover 4 which encloses them.

This cove-r member 4 provides a dead air space in which the heating elements above 'described are located, and by which the heat is conserved, the dead air serving as a heat This feature is also carried out in connection with the heating elements themselves.

Access is gained to the heating units by lifting up the cover member 4 for which purpose the toaster and waiile irons must be removed, leaving, however, the heating units 11, 11a in place, whereupon any heating unit can be lifted out oi place or can be replaced. By simply lifting the heating units out of place the top plate can be cleaned.

The cover Vmember 4 may be held in its raised position by arms 24 pivot'ed at 25 tothe depending sides 5 ot the cover. These arms are provided with hooks 24a which engage slots or openings in the` vtop plate of the main body 1 by which said cover will be held down. y

When, however, the arms are turned on their pivots by grasping and turning the finger pieces 24b on the outside of the cover and attached to the pivots of the arms, said arms can Vbe manipulated to release the catches or hooks 24a from engagement with the top plate 1 and the arms can be set in position to support the cover in elevated position, the end portions 24c ot the arms having been brought to bear on the top plate 1.

The front body panel 25X and the baci; plate 26 of the stove are or" sheet metal like the main body and like the cover member 4 and the casings of the heating elements above described and also like said parts they are stamped `to shape. The front panel or stamping is provided with an opening to receivethe oven 28 within the main body of the stove, the door of' which is indicated generally at 27. The back plate, the front panel and the main body 1 are held together by rods 29 and screws 30.

A bead strip 31 is inserted between the meeting edges of the main body 1 and the acl; plate and also between the main body and the iront panel or frame.

The main body is bent or shouldered at 32, Fig. 4, leaving a rim portion 32a and the bead strip hasv a channelled portion 32b embracing this rim portion and fitting against the shoulder whence the bead extends out- \\\'ardly and isv rounded or curved at its outer portion 31 to engage the 'flange 32 of the adjacent member, back or front panel7 the said iiange tit'ting against the channelled portion of the strip. This bead not only provides a iinish for 'the joint or meeting edges of the members and hides any raw edges of the white enamelled parts but also serves to strengthen the joint by reason of ther reinforcement afforded-against inward displacement.

Each bead member is made in one continuous piece or strip. This strip has its inner flange cut away at 32X, Fig. 7, at the point where the strip is carried around the corner of the body. ./it this point the wall of the body 1 is curved as shown at 1", Fig. 2, adding strength to the structure as well as to its iinished appearance. This bead Vstrip is sl aped to the form of an open frame corresponding to the cross sectional shape of the body 1 and in assembling the parts it is slipped onto the edge of the body, then the back or -front plate of' the body is slipped into its place in the bead and thereafter the tie rods 29 are placed in position, and all parts are drawn together.

iilithin the main body 1 the oven member 28 is supported in spaced apart relation to the top. bottom bach and sides thereof. This oven member is composed of inner and outer sheet metal walls with a dead air space between them at the top, sides, back and bottom of the oven. There is a ventilator at Z in the front door for ventilating the space within the oven. s

The. rear wall of the oven is formed of spaced apart sheet metal members 28", 28", Figs. 3 and 4, with a dead air space for heat insulation. The back plate 28a is Lll) till

vthiclrness of material..

shouldered at 28 and ianged at 28d t0 bear against the inner side of the main wallsof the oven and these joints are welded. The back plate 28 is anged at 28e to embrace the outer wall of the oven, but need not be welded at this point because this back plate is mechanically held as will be described. The oven is insulated against loss of heat both by the dead air space between its walls and also by thedead air space between the oven body and the wall 1 of' the main body oit the stove.

This feature of insulation by dead air is carried out as above described in connection with the upper burners, both by reason of the casmgs enclosing the heating elements proper and because of the use of the cover men'iber 4.

The oven `is supported at its rear end in spaced apart relation to the back of the .main body by two screws or bolts la. This leaves a dead air space for insulation against the escape of heat at the rear of the stove.

The bolts have each a rectangular portion, with a spacer l? between the shoulder thereof and the inner side ot the back wall 28 ot the oven. Nuts l.' on bolts l'L hold back wall E28" against spacer 'lC and there is a spacer l" between nuts 1f and the hollow nut or thimble, which is threaded on the holt and forms the connection between it and the rear wall ot the body l.

The oven is supported at its front end in the panel member for which purpose said panel or front member is stamped to provide a seat at E25 oit curved form to receive the rounded surface of the turned bead or edge E28( on the member 28g which forms the front end or portion of the oven proper. This bead is formed on a fiange projectingy 'from the said member 28g. This member 528i" is secta-ed to the walls of the oven by .its bead E28t and by a weld at 28j, and it is curved to provide a scat for the door. This door 27 is hinged at its lower edge to the 'front body panel 25 at 35 and it is com osed of: a 'trout portion, a panel 27a, a bacv 34" curved to tit the curved seat at the front of the oven, and an. intermediate member 34h. These members of the door are held together by their interlocking fianges at 34 and by male and female `screws 34X which connect the door members 27X, 27, 34, and 34", and malte a rigid door structure. These screws are located. near the corners of the door structure. The inner heads of these screws are countersunk in recesses formed in the piane or tlange portions of the members 34, 34, where these contact and make a double The part 28g of the oven and the inner plate 34a of the doorare stamped out in the same die at the same time so that they will lit perfectly where they contact with each other.

A door of the construction described provides two ldead air spaces, one on each side of the central plate or member 34b and these spaces provide heat insulation .at these points.

By my construction the insulation of the oven against the loss of heat is carried out to a maximum degree. The features entering into this are the double Wall construction of the oven itself, with a dead air space between its walls, also the dead air space between the oven and the wall of the body and the further dead air space between the top ot the body and the cover member 4, which with the dead air space 'over the top of the oven provi-des, together with the dead air space between the top walls of the oven itself, a triple dead air space against the loss of heat upwardl from the oven, and at the front the double ldead air spaces of the door provide :for heat insulation here. The oven .is removable and can be drawn out or pushed into place as one body.

lVhen pushed into the main body, it engages `inclines on terminal block 51 or skids 36 which raise it to the proper level properly spaced from the bottom of the main body. and also properly positioned to receive hoilow nut or thimble for holding the oven in place and ettect alignment of insulator block 49 between rear ends of oven and blocks 50, carried by main body, said blocks 50 supporting contacts whereby current will be supplied to the heating coils with which oven is provided, as will be described. The front portion of the oven maybe said to have a self adjusting action, the opening in the panel member 25 and seat 25a, being slightly larger than the bead and outer sheet metal wall of oven.

This construction is therefore one in which the front end oit the oven while held in position to receive the door within its recess will have a slightv Hoating or accommodating action to make it conform to any slight misaligninent with the part of the door which enters its recess and'makes a tight joint.

The door when lowered to substantially a horizontal position to gain access to the oven is held in this posit-:ion by side rods 37, which are pivotally connected to the door by semi-spherical members 38 fitting in recesses in the door frame, said rods having springs 39 connected to their inner ends and to the rear wall of the main body of the stove by which the door is under stress tending to balance or close it.

These rods and springs lie in the space between the sides of the oven and the sides of the main body.

The sockets in which the hemispherical pivots 38 work are formed in the double thickness oit' metal provided by the contact` ing flanges of the members 34, 34h. There is a clip 3S at each of the hemispherical frontpivot bearings 38 of the rods 37, which clip engages the back or square shoulder on the hemisphericai members. The lowered or horizontal position of the door is determined by the'plate 87h on the rod 37 coining against the inner side ot the iront 'all 525 and acting as a stop. This plate has the spring 3J connected thereto.

In order to take out the oven it is necessary to drop the front downv further than normal horizontal or lowered position, and for this purpose the rods which support the oven door in lowered position are pro`- vided. With knurled portions- 37 by which the rods may be turned and disconnectec from-the nut-s 38 andthe door then can be lowered far enough to not obstruct the oven in its removal.

The door is provided vfitha hand'le by which it may be manipulated. c

This handle as well as its keeper 39 is made of sheet metal stamped up into shape. The handle comprises: a cross lbar 39" of channel torni with arms 39C extending tor Ward. Between the front ends ott these the handle proper or grip 39d is' secured. The cross bar presents end walls which receive the pivots 39f which are supported by bracket arms or ears 39g. These have base portionsBQh on the inner side ot the it'ront wall of the stove door to which they are screwed, the said arms passingthrough slots in the front Wall.

The cross bar of the handle has an iuregra'l extension 391' bent upwardly and then downwardly with a rounded upper portion Vto engage under a lip 39 stamped from a part of the keeper 39 which is secured to the front member of the stove.

The oven is provided with upper and lower 'electric heaters 42, L1-3, but: as-the specific form ot these heaters not claimed herein, but in another application, they are not illustrated nor described in detail. racks 44. are provided -for receiving the coolving utensils at different heights.

In removing the oven from the main body for cleaning, repair or replacement, the electricl heating units 4:5 are first removed, thus rei'rovingr their contacts from engagement with complementary contacts.

At the rear corners ot the stove cover d platforms L1 are provided to give additional space for cooking utensils not in imn'iediate use or when the'cooking operation has been completed. -These platforms may be turned horizontally to overlie the cover member or they may be removed by lifting them from their. pivot bearings. To turn them over the top of the cover member 41 they are i1 rst lifted slightly from normal position.

The stove is specially adapted to be mounted on brackets or a bracket frame. 93 Which is to be secured to the Wall and the the stove is thus elevated from the tloor and has the space beneath it entirely tree.

This bracket frame is composed ot arms 911, made ot' one piece ot fiat sheet metal with side portion 95 curved backwardly and downwardly, vpreferably perforated, and having the top and rear edges flanged inafardly at right angles to said side portions. The pair of side bracket arms are connected :it the rear by a cross-bar oit angle iron 9'?, the ends of the horizontal llangc ot which lit under the horizontal flanges ot the arms 94 and its vertical lia-nge rests against the trout side ot the vert-ical flanges o1' the arms 91. ln other words, the angle iron cross-bar 97 tits in the rear upper corners Where the tlangeso't bracket arms 9de join each other. The side bracket arms are held together by three tie rots 99 passingjgthrough spacer tubes 98. On the rear tie rod, at each end, there is a washer 10() bearingion the inner side of the flanges of cross-bar 97 and holding crossb-ar in place. f

(ln this rear cross bar there are clips 102 which embrace the forward edge of the horizontal flange ot' said cross bar and have upwardly extending portions adapted to be screwed to the studding` ot the wall ot' the kitchen.

These clips are free to be moved along the rear cross bar to ysuit the position ot the studding. .lf the stove is to be supported from a brick Wall, expansion bolts may be used. The horizontal arms of the brackets are provided With upwardly extending bosses 103 which are to lit up into the retormed in the bottom oli the stove. Then the stove is mounted on brackets thebosses 103 project up through openings in the bottom of the stove. These openings have their edges turned upwardly slightly. The bosses 103 may be in the 'form of sheet metal shells Welded to the bracket. Bolts 103X passing through the bosses and resting on the flanged edges of the openings and Within the body hold the stove body to the metal Jfront member, and having a door opening, a stamped sheet metal door hinged to 'thebody, an oven Within and spaced apart from the body and supported at its frontend by the front member, a heater Within the oven, and tie rods extending from front member to thev back member through the space between the oven and the lltl it l) body for holding the main body, front and back together, siibstantially as described.
